AVS Response Codes

Overview

The payment processor's Address Verification System (AVS) validates address information in a credit card transaction and sends a response code that indicates the results of the validation check. It is typically considered a significant fraud risk to accept an order if the AVS returns a validation failure code.

These response codes are provided for informational purposes only and are subject to change without notice. Approval should be determined using the authorization response code and not be based on these specific response codes.
